The invention relates to a method and device for updating network community information issuing time and a server. The method comprises: determining the type of a thread according to a received thread operation request; and updating the last issuing time of the thread according to the type of the thread. The server may determine the type of the thread corresponding to the user operation, and update the last issuing time of the thread according to the type of the topic thread. In the case of the type of a thread which can be checked or downloaded just by a replied message, a user is not required to issue a replied message by himself/herself and the server automatically updates the last issuing time so as to maintain the popularity of the thread and optimize user experience.
